APPARATUS FOR COATING CONTAINERS.

Specification of Letters Patent.

Patented Dec. 23, 11919.

Application filed March 6, 1918; Serial'No. 2?;0,733.

To all whom it may concern:

Be it known that we, THEODORE 1L. VA- LERIUS and OLAF LARSEN, c1t1zens of the United States, residing at Fort Atkinson,-

construction and arrangement, which will effectively accomplish the desired result.

Another object of the invention is to provide an apparatus for coating receptacles which is very rapid, economical and otherwise eflicient in operation.

A further object of the invention is to provide an apparatus wherein steam employed for liquefying the paraffin may be utilized to actuate the coating means.

The objects of the invention thus generally stated, together with other and ancillary advantages, are obtained by the preferred embodiment of the invention illustrated in the accompanying drawings forming part hereof, in which Figure 1 is a central vertical sectional view throu h the apparatus with an inverted butter tu supported in position thereon, and showing the manner in which the parafiin is applied to the interior of the tub. Fig. 2 is a top plan view of the apparatus. Fig. 3 is a sectional view taken on line 33 of Fig. 1. Fig. 4 is a sectional view taken on line H of 410 Fig. 1.

\ Generally stated, the apparatus comprises an outer casing 1 transversely partitioned to form a paraffin container 2 and asteam chamber 8; an inner casing or cylinder 1 within the container 2 andhaving an impeller 5 therein; a turbine wheel 6 within the steam chamber arranged to drive the impeller 5; and a table 7 mounted on the cylinder 4; and arranged to support a tub A in position to receive a coat of paraflin drawn from the container .2 and forced out, in the form of a spray, through the upper end of the cylinder 4 by the impeller 5.

The casing 1 is substantially cylindrical in form and spaced a substantial distance within its lower end is a transversepartition 8 which forms the bottom wall of the container 2 and the top wall of the, steam chamber 3. Preferably, the partition 8 is shaped to form a steam dome so that the steam will more efiectively impart its heat to the container 2 to liquefy the paraffin. The lower end of the steam chamber 3 is closed by means of a plate 9 suitably secured to the lower end of the casing 1 as by means of bolts 10, and suitable legs 11 for the apparatus may be formed integral with the bottom plate 9 at spaced intervals throughout its periphery. 12 is a threaded opening leading from the lower end of the container 2 and arranged to receive a drain cock (not shown).

Centrally disposed within the container 2 in upright position is the inner casing or cylinder 1. Said cylinder is mounted upon a base 13 comprising a circular plate 13 having a plurality of spaced supporting blocks l3 at its periphery. The lower end of the, cylinder is provided with an outwardly extending flange 1 1, and bosses 15 are formed on the upper surface of the partition 8 upon which the supporting blocks of the base 13 are adapted to rest. Cap screws 14* passing through openings in the flange 14c and in the blocks of the base, and threaded into the bosses 15 serve to secure the cylinder 4 in position in the container. The circular plate of the base thus forms a bottom wall for the cylinder spaced a short distance above the partition 8, and said wall is provided witha central opening 13 through which the cylinder communicates with the container 2. The upper end of the cylinder 4; protrudes a short distance above the upper end of the outer casing 1 and is closed by means of a top wall 16 having near its periphery a plurality of equidistantly spaced outlet openings orports 17.

Mounted within the cylinder 4 upon a vertical shaft 18 is the impeller 5. Said impeller is of suitable construction, being herein shown in the form of a substantially rectangular frame having an upper hub 19 fixed to the shaft 18 and a lower hub 20.

The shaft 18 is arranged to operate within' a sleeve 21, the lower end of which is mounted in a boss 22 formed on the partition 8, and which extends upwardly in the cylinder to the lower end of the upper hub 19 of the impeller. Y The opening in the lower hub of the impeller is of sufficient size to freely receive the sleeve 21, and the upper hub of the impeller is fixed to the shaft 18 by means of a nut 23 threaded on the upper end of the shaft and clamping the hub against a shoulder 18 on the shaft; The upper end of the shaft 18 extends into a bearing 24.

formed in the upper wall 16 of the cylinder.

The lower end of the shaft 18 extends downwardly through the steam chamber 3 into a bearing 25 formed on the bottom plate 9 of said chamber, and within the chamber the shaft has fixed thereto the turbine wheel 6. Said wheel may be of any preferred construction and is provided at its periphery with a plurality of buckets or pockets 26 which are arranged to receive the impact of steam entering the chamber through an inlet opening 27 (Fig. 2) and discharging therefrom through an outlet opening 28. Said openings are arranged at opposite sides of the chamber 23 tangentially of the periphery of the turbine wheel, and the inner end of the inlet opening is restricted to form a jet or nozzle 29 which terminates in a thickened arcuate portion 30 of the chamber wall immediately adjacent the periphery of the turbine wheel. The steam entering through the opening 27 thus is effectively directed against the pockets 26 of the turbine wheel to drive the same and also the impeller 5 at high speed. Preferably the lower end of the shaft 18 is mounted upon a bearing ball 31 supported on the upper end of a screw 32 threaded into the lower end of the bearing 25 in the bottom plate.

It will be apparent that the steam admitted into the steam chamber 3 quickly heats the paraffin in the container 2 and reduces it to liquid form, and that the turbine formed by the chamber 3 and the wheel 6 is actuated by the steam, when the parafiin has been thus liquefied, to drive the impeller 5, but the steam is prevented from entering the container. The impeller, in turn, drawsv the liquefied paraffin from'the container 2 through the opening 13 in the base 13 and into the cylinder 4 and forces it upwardly in the form of a spray through the ports 17 in the top wall 16 of the cylinder.

The table 7, however, which is arranged to support a receptacle to be coated, such as the inverted tub A, serves to control the flow of the parafiin through the ports 17. Said table is supported uponthe upper end of the cylinder 4 and comprises a central bearing plate 33 having a downturned rim flange 34 and a plurality of radial arms 35 arranged to support the tub. The rim flange 34 fits neatly around the upper end of the cylinder 4 and the plate 33 is provided near its periphery with a plurality of openings 36 arranged to be brought into register with the ports 17 in the upper end of the cylinder 4a A rotation of the. table, however, will carry the opening 36 and the ports 17 out of register, and-thus the flow of parafiin may be cut off. 1 To one of the arms 35 of the table'is secured a handle 37 which extends radially outwardly and upwardly over the adjacent rim of the outer casing 1 and in sliding contact therewith, and preferably a pair of stops 38 are secured to the rim of the casing 1 at opposite sides of the handle 37 to facilitate the positioning of the table so as to permit or prevent the spraying of paraffin as desired.
